Applications

​

Polyvinyl butyral interlayer is a thin film of uniform thickness that has been processed and extruded from PVB resin mixed with plasticizer and additives. Its unique characteristics are: impact resistance, penetration resistance, sound insulating, and UV-proof. Moreover, PVB film can hold the debris from shattered glasses to protect the end users. Currently, most automotive windshields are required to adopt PVB laminated glass. PVB films are also used for the glass on high-rises and landmark architectures and Solar panels.

Interlayers are used to permanently bond two pieces of glass in a laminated configuration. PVB Laminated glass offers many additional advantages over traditional annealed glass:


Acoustic – Reduces noise transmission due to the sound damping characteristics of the interlayer

Aesthetic – Offers a selection of color and opacity not achievable with other glass products.

Blast-Mitigating – Provides a variety of  options that help mitigate the effects of air-blast attacks.

Hurricane-Resistant – Hurricane resistant laminates offer improved impact and wind pressure resistance.

 

Safety - WINLITE PVB interlayers comply with ANSI Z97.1-1984 and CPSC 16 CFR 1201, which are the industry safety standards for glazing materials.

 

Ultraviolet Protection – Laminated glass can provide up to 99% UV light blockage

PVB film is widely used in automotive safety glazing applications such as windshields, head-up-displays or sun-roofs.

 

Taking advantage of the variety of benefits PVB has to offer including heat, weight, and sound reduction as well as safety, security, and UV protection, PVB film has been the quality and reliable foundation for car windshields for almost 100 years. Glass fabricators and automotive engineers continue to count on PVB film in their automotive laminated glass process.

PVB film as an encapsulation material for solar cells, is a thermoplastic that does not cure on exposure to heat and hence displays reproducible lamination behavior.
